Argentina had diesel-electric submarines while the British had nuclear-powered submarines.
Nuclear Energy
Nuclear submarines are powered by a nuclear reactor and they are completely independent of air, so there is no need to surface frequently.
The PLA navy has more than 225,000 personnel and is thought to have as many as 70 submarines, 10 of them nuclear-powered
Yes. Nuclear power plants and nuclear powered ships and submarines use controlled fission reactions.
The main advantage to having nuclear powered submarines is that a nuclear powered submarine can, if designed wisely, stay submerged for months on end. The only limitation really is food and the crew's psychological state. This is extremely useful in nuclear deterrance considering that a nation can send out nuclear powered, nuclear weapon equipped submarines on patrol for use in case of a nuclear exchange. If an attacking nation destroys the missiles silos of it's target and it's nuclear armed bomber wings, the defending nation would still have the use of it's nuclear weapons onboard it's ballistic missile submarines.

It is doubtful. Canada has never had nuclear powered ships or subs. the current submarines (victoria class) were acquired from the UK and are desiel powered. Canada does not have any plans in the future for any nuclear power vessels.
The Los Angeles class submarine is nuclear powered.
USA. nuclear powered submarines can go faster than 25 knots (nautical miles per hour) underwater.
Most records about Nuclear Powered aircraft are classified, just like the Nuclear Submarines. The United States has only published one record of a Nuclear Powered aircraft. The program was cancelled in 1958, due to complications.
Submarines are powered by diesel fuel (in the past) or more recently by nuclear reactors. Nuclear reactors provide advantages in range and in noise produced.
